Instead of binding rename_node, I needed to bind to rename.jstree, and then needed to use rollback of action.

Here the bind event code.

if(type === 'rename')
{
        var new_Name = data.rslt.new_name;
        var iChars = "!@#$%^&*()+=[]\\\';,/{}.-_|\":<>?";
        for (var i = 0; i < new_Name.length; i++) 
        {
            if (iChars.indexOf(new_Name.charAt(i)) != -1) 
            {
                alert ("Special characters are not allowed.");
                $.jstree.rollback(data.rlbk);
            }
        }
 }

You can also do it through rename_node. If validation fails call:

$('#yourtreeid').jstree("refresh");
